1.0 Introduction
Hot rolled AISI 304 stainless steel sheets 32” wide are to be reduced from 9 to 30
gauge while maintaining a constant width. Design will be based on tandem rolling
operation without intermediate annealing. The goal of this project is to design a robust
manufacturing process that fulfills all design requirements in geometry, thermal
properties, lubricants, and velocities.
2.0 General Design
Understanding we needed to reduce thickness, we initially researched actual
dimensions for 9 and 30 gauge to calculate total required reduction. From Citation we
found 9 and 30 gauge to be .1495 inches and .012 inches, respectively. This is a total
reduction of roughly 90%. Researching common processes for sheet gauge reduction,
we considered cold rolling.
Cold rolling allows for a total reduction varying from 50-90% while increasing
strength and surface finish. Cold rolling usually requires multiple rollers, typically
ranging from 10-30 inches in radius, and multiple passes allowing roughly 20-40%?
